Centre Console Rattle?

Hi guys,

Well, with 1200 miles on the clock my Yeti is now nicely starting to accumulate it's share of squeaks and rattles (I don't even go offroad), most I can put down to the cold weather, for now at least, but one in particular is bugging me - it's a noticeable "knocking", plastic-on-plastic type rattle, from around the area behind the main info screen/stereo. I've read about most other variations of rattle, of which I seem to have my share, but this one I haven't heard about! Any ideas? I'd guess any kind of fix is going to require removing the head unit in some way though...  :|
